Which group of elements on the periodic table is characterized by having few valence electrons and is known for conducting heat and electricity?
A
Halogens
B
Alkali metals
C
Transition metals
D
Noble gases
Verified step by step guidance1
Identify the key characteristics described in the problem: elements with few valence electrons and good conductors of heat and electricity.
Recall that elements with few valence electrons (usually 1 or 2) are typically metals, which tend to be good conductors.
Review the groups listed: Halogens (group 17) have 7 valence electrons and are nonmetals, so they are not good conductors.
Alkali metals (group 1) have 1 valence electron and are excellent conductors, but the problem suggests another group.
Transition metals (groups 3-12) have variable valence electrons, often 1 or 2, and are well-known for their excellent conductivity of heat and electricity, making them the correct group.
